For example, here are the row pitch measurements in the 737-900ER cabin currently mapped
First class rows 1 to 4: pitch = 39.5"
Premium class rows 6 to 9: pitch = 34.5"
Main cabin rows 10 to 15: pitch = 31"
Overwing exit rows 16 and 17: pitch = 37.5"
Port side (ABC) rows 17 to 32: pitch = 32"
Starboard side (DEF) rows 17 to 34: pitch = 30.5"
This is surprising to me as well, at least the part about port seats in Main having noticeably greater pitch than starboard seats. I'd never heard mention of this discrepancy before. But I guess I will need to remember to favour the left side of the plane whenever I'm in Main.
Also, it looks like you need to make a minor correction in the table above. Row 17 shows up as both an exit row as well as a non-exit row. I noticed the repeated row 17 for each of 737-900, 737900ER, and 737-MAX9.
